SGER: Cerro Grande/Viveash Fire Research Project

0104202 Tierney最近在新墨西哥州的Cerro Grande和Viveash野火提供了一个独特的机会来研究两种不同森林类型的密集再生努力的早期影响。今年夏天，超过720，000点的种子，其中大部分是非本地的草，被应用到Cerro Grande烧伤现场。同样，230 000磅种子也被用于Viveash场地。文献回顾表明，生态研究评估的影响重新播种，特别是与非本地物种，还没有进行这样的西南森林生态系统。该项目将监测野火后头两个生长季节引进、播种和火灾后本地新兴物种的建立和分布。在这项探索性研究中收集的数据将被用来测试空间明确的模型，预测模式的分布和持久性之间的引进和本地植物物种在播种和未播种烧毁的地区。这些模型是有用的，在检查的长期有效性重新播种和引进非ntaive物种的恢复和演替模式中海拔黄松和高海拔云杉/冷杉林系统的影响。

0104202TierneyThe recent Cerro Grande and Viveash wildfires in New Mexico provide a unique opportunity to study the early effects of intensive regeneration efforts on two distinct forest types. Over 720,000 poinds of seed, most of which was non-native grasses, was applied to the Cerro Grande burn site over this summer. Similarly, 230,000 pounds of seed were also applied to the Viveash site. Review of the literature suggests that ecological studies evaluating the effects of reseeding, particularly with non-native species, have not been conducted in such southwestern forest ecosystems. This project will monitor the establishment and distribution of introduced, seeded and post-fire native emergent species in the first two growing seasons following the wildfires. Data collected in this exploratory study will be used to test spatially explicit models that predict patterns of distribution and persistence among introduced and native plant species in seeded and unseeded burned areas. These models are useful in examining the long-term effectiveness of reseeding and the effects of introducing non-ntaive species on patterns of recovery and succession in mid-elevation Ponderosa pine and high-elevation spruce/fir forest systems.
